Opinions please?

Before anyone comments, I'd just like to say that I'm not looking for attention, or trying to cause a ruckus. I am merely looking for advice💗Thank you ladies.
    I am 14, and I have a close friend who is 17. I trust him and I know he is a good person who just wants the best for me. But lately I've been having feelings for him, and I think he may have feelings for me, too. I'm just really unsure about the whole thing because, he's older, and my mom doesn't approve. I know I sound like some immature, irresponsible teen right now,😅 but I don't want to be with him for the wrong reasons. I'm not looking to loose my virginity or do bad things, I just really want to be with him because of who he is. He's honest, a good person, and someone I know who is going to respect me.
   Am I being totally irrational😆? I'm a straight A student and I'm very responsible. I just know that my mom doesn't approve of him.... Please help🙏🏼Thankyou!
